Abstract: An energy absorbing device (40) includes a plastically deformable metal strap (46) for resisting the collapse of a steering column (44). The strap (46) is initially deformable into one or more V-shaped wave formations (51) by anvils (48, 50) to increase the energy required to advance the strap (46), thereby increasing the resistance to collapse of the steering column (44). One of the anvils (48) may be removed to eliminate one of the wave formations (51) and thereby reduce the amount of resistance to collapse of the steering column (44). Alternatively, the position of an anvil (72) may be varied to vary the shape of a wave configuration from a deep V to a shallow V.

Abstract translation: 能量吸收装置（40）包括用于抵抗转向柱（44）的塌陷的可塑性变形的金属带（46）。 带（46）最初通过砧座（48,50）可变形为一个或多个V形波形结构（51），以增加前进带（46）所需的能量，从而增加转向柱塌陷的阻力 （44）。 砧座（48）中的一个可以被移除以消除波形形成（51）中的一个，从而减少转向柱（44）的塌陷的阻力的量。 或者，可以改变砧座（72）的位置以将波形的形状从深V变化到浅V。
